NB This site is under active development, current content in the main database is primarily from Bolli et al 1994, Hayward et al. 2012, Holbourn et al. 2013, Holbourn and Kaminski 1997, Alegret & Thomas 2001, and Katz et al. 2003. It is intended to expand and develop this to provide rather comprehensive coverage of Mesozoic and Cenozoic deep-sea benthic foraminifera.

NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.

Geological Range:
Last occurrence (top): within (-Ma, top in "Holocene" stage). Data source: Total of range of species in this database
First occurrence (base): within Cretaceous Period (66.04-143.10Ma, base in Berriasian stage). Data source: Total of range of species in this database
